Prosthetic capsular devices, systems, and methods
Prosthetic capsular devices (e.g., bag, bowl, housing, structure, cage, frame) include technology devices such as a computer, virtual reality device, display device, WiFi/internet access device, image receiving device, biometric sensor device, game device, image viewers or senders, GPSs, e-mail devices, combinations thereof, and/or the like. The technology devices can be used in combination with an intraocular lens. The output from the technology device(s) can be fed to the retina of the user to provide a visual image, can be otherwise connected to the user, and/or can be used to control the properties of the intraocular lens or of the prosthetic capsular device. Wearable technology that provides biometric data, such as blood glucose levels, body temperature, electrolyte balance, heart rate, EKG, EEG, intraocular pressure, sensing ciliary muscle contraction for accommodation stimulus, dynamic pupil change and retinal prostheses, combinations thereof, and the like can assist in technology-assisted health care functions.
1. A prosthetic capsular device configured to be inserted in a natural capsular bag of an eye after removal of a lens, the device comprising:
a housing structure having a discoid shape configured to contain one or more intraocular lenses or technology devices, the housing structure comprising:
a longitudinal axis;
a posterior side;
an anterior side opposite the posterior side, the anterior side comprising an anterior opening having rounded edges;
a continuous lateral side extending between the posterior side and the anterior side, the continuous lateral side comprising one or more protrusions projecting radially therefrom, wherein the one or more protrusions are continuous around a perimeter of the device;
a cavity at least partially defined by the posterior side, the anterior side, and the continuous lateral side, wherein the cavity is configured to contain the one or more intraocular lenses or technology devices, and wherein the anterior opening is configured to allow insertion of the one or more intraocular lenses or technology devices into the cavity of the housing structure through the anterior opening; and
an exterior surface of the housing structure comprising a straight-walled portion extending parallel to the longitudinal axis from the posterior side towards the anterior side, wherein the exterior surface of the housing structure tapers radially inward from the straight-walled portion to the anterior opening.
2. The prosthetic capsular device of claim 1 , wherein the continuous lateral side comprises one protrusion.
3. The prosthetic capsular device of claim 1 , wherein the continuous lateral side comprises more than one protrusion.
4. The prosthetic capsular device of claim 1 , wherein the prosthetic capsular device comprises a biologically-compatible material.
5. The prosthetic capsular device of claim 1 , wherein the prosthetic capsular device is deformable.
6. The prosthetic capsular device of claim 1 , wherein the prosthetic capsular device is foldable.
7. The prosthetic capsular device of claim 1 , wherein the prosthetic capsular device possesses sufficient elasticity to resume its pre-folded shape.
8. The prosthetic capsular device of claim 1 , wherein the prosthetic capsular device is self-expanding.
9. The prosthetic capsular device of claim 1 , wherein the prosthetic capsular device comprises an optically clear material.
10. A prosthetic capsular device configured to be inserted in a natural capsular bag of an eye after removal of a lens, the device comprising:
a housing structure having a discoid shape configured to contain one or more intraocular lenses or technology devices, the housing structure comprising:
a longitudinal axis;
a posterior side;
an anterior side opposite the posterior side, the anterior side comprising an anterior opening having rounded edges;
a continuous lateral side extending between the posterior side and the anterior side, the continuous lateral side comprising a protrusion projecting therefrom;
a cavity at least partially defined by the posterior side, the anterior side, and the continuous lateral side, wherein the cavity is configured to contain the one or more intraocular lenses or technology devices, wherein the anterior opening is configured to allow insertion of the one or more intraocular lenses or technology devices into the cavity of the housing structure through the anterior opening, and wherein at least one of the one or more intraocular lenses or technology devices comprise a technology device;
an exterior surface of the housing structure comprising a straight-walled portion extending parallel to the longitudinal axis from the posterior side towards the anterior side, wherein the exterior surface of the housing structure tapers radially inward from the straight-walled portion to the anterior opening; and
an insulation structure that thermally insulates the eye from heat produced by the at least one technology device contained in the cavity.
